FloPlast SP558G Waste Manifold Grey is rated 4.7 out of 5 by 7.
Rated 4 out of 5 by from Useful bit of kit. This manifold is very useful in achieving multiple waste connections at a low level into a stack. If you are trying to use a 2" waste it is not clear from the items description that you have to re-cut the hole and buy a different rubber boss adaptor , which screwfix sells but I can't see them in their catalogue. I don't think that it would be easy for an everyday DIYer.

Rated 5 out of 5 by from saves lots of fowl connections simple to install and makes connecting a number of waste pipes to the SVP easy. Connected bath, WHB and a condensate drain leaving one spare. Looks tidy and seems to work. Can be adapted to take different pipe sized waste pipes by trimming the rubber seal back. Has to be used in the orientation shown and mine isn't 100% air/water tight but it doesn't leak: Probably adds to the venting

Rated 4 out of 5 by from Take care with the seals As others have said this is a very useful fitting. It is over 90° from face to face but this takes into account the spacing from the wall when pipe brackets are used. If it's tight chase the wall out and rotate it a bit - don't chop into the joist as one reviewer says. Based on experience a word of warning about the smaller seals: Hold them in place both when inserting and removing a pipe. I lost a seal down the stack on pulling a pipe out of it. Managed to recover it later with the help of a sieve on a stick but you might not be so lucky.

Rated 5 out of 5 by from Best fit for limited space Well designed and good value for money product. Incorporates a flush to soil pipe design, so it fits tight into a corner or against a wall. Eliminates the need for additional boss adaptors on the main pipe for up to 4 appliances.

Rated 5 out of 5 by from Great manifold Great manifold, great valve for money, low profile/low level, multiple ports, just what I needed.

Rated 5 out of 5 by from A nice solution I needed something like this to connect up bath, shower and basin wastes below a wc connection but where there was limited space. I tried one from tool station that had a rib all around where the top and bottom halves of the chamber met that fouled on the adjacent joist. This looked like a better prospect as the chamber is flush with the line of the outside of the pipe. One thing that was not obvious from the picture is that the angle between the two straight faces is significantly more than 90 degrees to accomodate the four inlets. I had to chop some material from the adjacent joist to make room. If it's bracketed off a wall then there should be adequate space for it.. As I said above it's a great solution and at a reasonable price. I cannot really comment on the performance or reliability yet but I have no reason to doubt that it will perform well.

Rated 5 out of 5 by from Great bit of kit This manifold is a very elegant way of organising your drainage challenges. It ensures that the toilet waste outlet does not affect the other wastes fitted into the manifold.
